    Considering the size of DuPont and the money they spend on advertising, you would think they could put out, and update, a better product.. Based on the lack of response to comments here, and updates (last update August 2012) I would say they aren't interested. If there was a link from the app for feedback I would use it. A disclaimer EVERY Time I launch the app. Data that is wrong when you change
